There was a guy who left his car keys in the car and called a locksmith to open the car, for $100. So the guy says “You see, this is a brand new Ferrari, worth $300,000, so if you make the slightest scratch on my car, it will lose $50,000 in value, and you’ll have to pay me $50,000”. Locksmith replies “I’m afraid you’ll have to walk home”.
Another guy booked a hotel room, then he complained that the $5,000,000 worth of diamonds in a little suitcase had disappeared from his room. And he wants the hotel to pay. So the hotel asks “did you tell us you would arrive with five million worth of diamonds? Did we accept responsibility? Because if you had, your room rate would have been $10,099 instead of $99, and we would have had armed guards inside and outside your room”.
